Check Digit Verification of cas no
The CAS Registry Mumber 7509-98-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,0 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7509-98:
(6*7)+(5*5)+(4*0)+(3*9)+(2*9)+(1*8)=120
120 % 10 = 0
So 7509-98-0 is a valid CAS Registry Number.
